Water Shortage Risk Index (WSRI) at the neighbourhood scale. The case of Mexico City

Water security is one of the main challenges that cities around the world face especially in Megalopolis such as Mexico City that struggle to provide safe and accessible fresh water to their inhabitants. The research project presents a Water Shortage Risk Index at the neighbourhood scale for Mexico City. The index is built into four main factors which are social, infrastructure, environment and innovation each of them with their respective levels. Each neighbourhood is compared to a synthetic neighbourhood that holds the ideal values for water security in urban contexts. The bigger the distance to the ideal synthetic neighbourhood the bigger the risk of water shortage in the neighbourhood. Once obtained the Water Shortage Risk Index it is compared with the already existing Urban Marginalization Index to obtain the most vulnerable neighbourhoods in Mexico City providing the areas that require the most attention in future water security projects and policies. The research aims to contribute to further exploring water shortage management at the neighbourhood scale that will allow local governments to implement more efficient projects and policies to reduce water shortage risk in Mexico City.
